FEE-DING DEVICE FOR WOOD-PLANING MACHINES.

SPECIFICATION forming part of Letters Patent No, 249,337, dated November B, 1881,

r Applicatioufiled June 27, 1881. (No model.)

To all whoin' it may concern:

Be it known that I, EDWARD F. GORDON, a citizen of the United States, residing at Goncord, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Feeding Devices for Wood-Planing Machines; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention relates to improvements in feeding devices for wood planing machines and the object I have in view is to obtain an increased spreading capacity in a vertical direction between the feed rolls, to enable the feed-rolls to be adjusted to and from each other for. feeding thick or thin stock; and with my device I am able to use gears of large diameters, thereby diminishing the strain on the teeth, studs, journals, &c., as well as imparting a more uniform motion to the feedrolls themselves. By my method of gearing I project the bed-rolls through suitable apertures in the side frames, by which said bed-rolls are allowed to move up and down freely, according to the thickness of stock that is being planed; and by locating the journals for the bed-rolls in the apertures aforesaid I obtain longer bearings for them at the same time as I get full lengths of the rolls under the cylinder.

The invention is carried out as follows, reference being bad to the accompanying drawings, on which-- Figurelrepresents a side elevation, showing a portion of the upper belt-pulley and outer intermediate gear broken off. Fig.2represents a' side elevation, seen from the opposite side to bearings in the upper part of the frames to and b in the ordinary manner. 7

e is the driving-shaft, and eits belt, by means of which a rotary motion is conveyed to the cutting 4 cylinder shaft d, as shown in Fig. 2. On the opposite end of the shaft 0 is a small pulley, f, that conveys a rotary motion, by means of thebeltf, to the pulleyg on the stud g, which stud is further provided with the small pinion 71, that gears into the spur-wheels I I, secured respectively to the shafts i z" of the upper feed-rolls, k, by which arrangement a rotary motion is imparted to said upper feedrolls. The bearings for the shafts t and 13 are secured, as usual, to the upper parts of the frames a and b, as shown in Fig. 2.

To the upper feed-rollshaft, i, is hinged the link I l, the lower end of which is jointed to the link m, as shown. 6.5

n is a shaft, having its bearing in one end of the link m.

To the shaft a is secured the intermediate spur-gear, 0, gearing into the teeth of the spurwheel I, as shown in Figs. 1 and 2. t 7o The inner end of the linkm is hinged on the central shaft, p, located in bearings on the bed 0, and a rotary motion is imparted to said shaft pfrom the shaft nby means of the intermediate spur-gear,o,secured to theinnerendof the shaft 7 5 n, gearinginto the teeth of the small pinion p on the end of the central shaft, p, that rises and falls with thebed c. To the opposite end of the central shaft, 19, is secured another small pinion, p", (shown in Fig. 2,) that gears into the teeth of the spur-wheels Q and Q, secured respectively to the shaft q and q of the lower feed or bed rolls, 4. The shafts q and q are located in bearings r, secured to the bed or table 0, and rise and fall with the latter within 8 5; apertures or slotted openings 8 and s. in the side frames, trend 1), by which arrangement I obtainlong bearings for the bed-rolls r, with full lengths of the latter under the cutting-cylinder;

Apertures]? P are made in the side frames, at and I), through which the central shaft, p,

projects, to allow of its vertical adjustment with and intermediate connecting mechanism from the gear-wheel I to the gears Q, and Q, 011 the bed-roll shafts q and q.

of the vertical adjustment of the bed rolls isobtained.

The bed 0 is adjusted in a vertical direction by means of the ordinary and well-known mechanism for this purpose.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. In aplanin g-machine, the herein-described feeding device, consisting of the pinion h, gearwheels I I on the upper feed-roll shafts, i 43,

intermediate spur-wheels, 0 and 0, on the link, pin, or shaft 11, the single combination-link l l m upon shafts i and a, the central pinions, p and 19",011 the central shaft, 19, and spurwheels Q, Q on the vertically adjustable bedroll shafts q q,said members being constructed and organized for operation as and for the purpose set forth.

2. In a planing machine, the combination, with upper and lower roll-shafts, 11 i q q, of expansive gearing device consisting of the gears 0 and 0, shaft 12, and combination-link l m, as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

EDWARD F. GORDON.
